Brazil's former leader Luiz Inacio Lula da Silva makes his return to politics attacking President Jair Bolsonaro, giving a scathing take-down of the incumbent's management of the economy and signature policies. Lula, who led Brazil from 2003 to 2010, has emerged as a top contender to unseat Bolsonaro, after a judge annulled the popular but tarnished leftist's corruption convictions, reinstating his right to run for office.
